In news:

Legislation passed with bipartisan support by the California State Senate and signed into law last week will now require water companies and agencies to be subject to the same review and audit process as other public utilities.

In science:

The ridged waveguides are machined into the cell, the slots by wire etching, the waveguide by milling. The SiC wedges are fixed with a specially designed clamp, avoiding thermal strains during brazing. Water cooling channels and dimple tuning are provided. The complete structure is brazed vertically and in one pass.

Carnot reasons by analogy with a machine that works at the expense of water passing from a higher to a lower level reservo ir.

The Energy-Entropy Principle

If the water could, by it self, pass into a higher level we would have a perpetual machine.

The Energy-Entropy Principle

Carnot associates the heat (or caloric) passing between two sources at different temperatures with the water falling between the two levels. The quantity of water falling to the lower level reservo ir is equal to the one coming out of the higher level reservo ir.

The Energy-Entropy Principle

The purity of the liquid Argon before passing through the OXYSORB cartridge has a nominal concentration of water and Oxygen of the order of the ppm.

The water containing impurities smaller than Gd and SO4 is deionized (DI) and then sent through the reverse osmosis (RO), where only H2O molecules can pass through the membrane.

Gadolinium study for a water Cherenkov detector

For electrons with a kinetic energy of 5.0 MeV passing through 1 cm of water, the percentage increase in the fraction that scatters into the forward hemisphere over that obtained with EGS4 is 0.9% when applying the average step length correction, and 1.2% using EGSnrc.

These simulations reveal the motion of a single water molecule as it passes through the channel.

Biological and synthetic membranes: What can be learned from a coarse-grained description?

The tra jectories provide insights into the speciﬁcity mechanism by which the channel allows water, but not ions, to pass.

Biological and synthetic membranes: What can be learned from a coarse-grained description?

In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions).

Extraction of Freshwater and Energy from Atmosphere

Thus heated, the water is passed to another container known as a "stage", where the surrounding pressure is lower than that in the brine heater.

Extraction of Freshwater and Energy from Atmosphere

The bars, which operate at ~1800 K and radiate the power dissipated in them to water-cooled walls, are connected to a pair of chains that propel and guide them through the solenoids. If there are ~500 bars on the chains, each target bar passes through the beam only one million times in one year of operation.

Thus Eqs. (3.28) and (3.29) are the constant fractions of the original energy E0 deposited into ionic energy EI and electronic energy Ee — the energy losses analogous to those of the water passing through the rocky waterfall.

The narrow selectivity ﬁlter is only 12 ˚A long and about 3 ˚A wide, which forces potassium ions with Pauling radius 1.33 ˚A to shed their hydrating waters to enter and pass in a single-ﬁle fashion.
